Small open-frame generators cover the essentials in an outage: a fridge, a freezer, a sump pump, lights and phone chargers, plugged in with extension cords or through a small 30 A inlet. Most have a TT-30 or L5-30 outlet, which feeds only one leg of a house panel, so a 240 V well pump or dryer is out of reach. They weigh 100 to 150 lb, so wheels and a folding handle matter.
